A more thorough explanation: In the context of self-defense, a “killer” refers to a person who causes the death of another individual in order to protect themselves or others from imminent harm or danger. This act is considered justifiable under the principle of self-defense, where the use of lethal force is deemed necessary to prevent serious injury or death.
Example: The defendant argued that he acted in self-defence when he shot the intruder, claiming that he was a killer within self-defence.
